Breast Cancer and Lifestyle

50 ribu wanita di diagnosis kanser payudara setiap tahun

One in eight women will develop breast cancer in their lifetime and the rate is rising, alarming figures show.Scientists blame obesity, alcohol and the growing tendency to delay motherhood for record levels of the disease.

Experts describe the figures as a ‘wake-up call’ and say thousands could avoid the disease if they drank less, maintained a healthy weight and took more exercise.

The rise has also been blamed on the fact that increasing numbers are delaying motherhood and consequently having fewer children. The figures show that there are now 124 cases per 100,000 women, twice as many as any other type of cancer.

Scientists believe some forms of breast cancer are triggered by the sex hormone oestrogen, which is linked to obesity, alcohol consumption, having fewer children and not breastfeeding

They also blame hormone replacement therapy taken by millions every year to combat the symptoms of the menopause.Doctors believe many tumours are caused by unhealthy lifestyles and are urging women to change their eating and drinking habits, particularly during the menopause.

Probable causes: Experts blame lifestyle choices such as alcohol and obesity, along with a growing wish to put off motherhood, for the spike in cancer rates.Research has found that obesity increases the risk of breast cancer after the menopause by up to 30 per cent. The overweight are also more likely to develop tumours.

Fat cells produce oestrogen and levels of this cancer-triggering hormone can be twice as high in obese women as those of a healthy weight.

Alcohol is also thought to raise the levels of oestrogen. Previous studies have shown that drinking even only one glass of wine a day can raise the risk of breast cancer by a fifth.

Women may also be increasing their risk by having fewer children, or none at all, because the levels of oestrogen decline during pregnancy. Those who delay motherhood and consequently have fewer babies will be exposed to oestrogen for a higher proportion of their lives.

The risk is elevated further because breast-feeding has been shown to protect against the tumours as it lowers the level of oestrogen and other hormone
